IMPROVEMENT IN MOLDS FOR CASTING HORSESHOES.

Specification forming part of Letters Patent No. 38,047, dated March 3],1863.

To all whom it may concern:

Be it known that I, JAMES KENNELLY, of Hartford, in the county ofHartford and State of Connecticut, have invented a new and Improved Moldfor Casting Horseshoes; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, in Which- Figure 1 represents a longitudinalvertical section of my invention; Fig. 2, a transverse vertical sectionof the saine. Fig. 3 isaplan or top view of the same, the upper half ofthe Inold having been removed.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in ainold for casting llorseshoes, which isprovided with a plate from which a series of pins rise, which carry thecores of the nailholes to be produced in the horseshoes, said platebeing adjustable by cams and levers in such a manner that on receivingthe plate all the cores of the nail-holes are made to project into themoldin the proper position to produce the nail-holes, and on depressingsaid plate allthe cores are withdrawn simultaneously, the Whole moldbeing so arranged that a complete horseshoe can be cast with all thenail-holes and with little trouble or labor in molding.

To enable others skilled in the art to make and use my invention, I willproceed to describe it.

A A represent the two halves of my mold, which is made of metal or anyother suitable material. Each half is provided with a cavity, a c', andon placing the two halves one on the top of the other the cavity ccovers the cavity a, and thehollow space thus formed has'the shape ofthehorseshoe which is to be produced. The correct position of the twohalves in relation to each other is insured by studs b, which rise fromone and project into holes in the other half. A spout, B, serves tointroduce the molten metal.

C is a plate, of iron or other suitable material,

which is held between two pairs of cams, D

D, under the lower half,A, ofthe mold. The

cams D D are secured to shafts E E', which have their bearings in lugsF, fastened to the under surface of the lower half of the mold, and saidcam-shafts are operated by means of a lever, 4G, which is attached tothe upper shaft, E, and which connects by a link, c,with a lever, G,secured to the lower shaft, E. By depressing the lever G the cam-shaftsare rotated simultaneously, and by the action ofthe cams the plate C isdepressed, and by raising the lever G the plate C is raised, and thecams D D must be so arranged that the motion of the plate is parallel tothe lower surface ofthe mold. The plate C carries a series of pins, d,which project into the lower half of the mold, and the upper ends ofwhich forni the cores e for the nail-holes to be produced in thehorseshoes. By raising the plate C these cores are brought in the properposition for casting, and

.by depressing the plate C all the cores are withdrawn simultaneously.

In casting horseshoes the mold is placed in the proper position, the twohalves being united, and the plate G is raised to bring the cores up.After the metal has been run into the mold, and as soon as it commencesto set, the cores must be withdrawn to prevent them from melting andadhering to the metal ofthe horseshoe, and when the metal has cooled offthe shoe is ready with all the holes. The casting of horseshoes isthereby rendered very easy, and a large number of shoes can be producedwith little labor in a short time.

What I claim 'as new, and desire to secure by Letters Patent as a newand improved ar-V ticle of manufacture, is-

A mold for casting h,orseshoes,provided with a plate, C, carrying thecores e for the nailholes, and adjustable by cams D D',as and for thepurpose shown and described.

JAMES KENNELLY.
